Complete Kinematics course made in MicroStation http://www.Bentley.com ; for deeper, intuitive learning without abstract formality and dry rigor for its own sake. • • This video shows two mechanisms (Paucellier and Hart) tracing exact straight lines based on a special case of inversion. The construction and proof are explained. The straight lines traced are shown by dragging and moving the mechanisms. • • 0:20 Paucellier mechanism (eight Bar) -- construction • 0:50 Working and proof of Inversion • 3:15 Limiting case of inversion • 3:40 Drag to move and trace path • 4:20 Hart's mechanism (six bar)
